To all w hom it may concern:

Be it known that I, O'r'ro 'MARKLiiIN, a citizen of the United States,and a resident of 'the'borough of Brooklyn, inthe city and State of NewYork, have invented certain new and useful Improvements in Tail-Gatesfor Vehicles, of which the following is a specification.

My invention relates devices commonly 'known'as tail gates or tailboards which" are commonly used at the rear ends of commerbeingpivotally attached thereload'or closed andsec'ured for the purpose ofretaining the load.

The ,obj ect of the invention is to provide ficient, and which shall becapable of either above its lower edge so as to swinging out-uponitsloweredge'into' a plane approximately the same as that of the floorof the vehicle so as to serve as an extension of the same and permit'theremoval of the load thereover, or to swing outward upon a' pivotal linelocatedsubstantially ermit the automatic discharge of the, loa under thetail .gate, a s is often desired in some forms of 1 dumping vehicles.

The invention consists in the ,novel con-" struction, arrangement andcombination of various elements and parts as hereinafter fully.described andas' shown in the accomanying drawings. i

Inthe said drawings, Figure 1 is an elevation of. a tailgate constructedaccording to my invention, showing the sa e' adapted to swing upon itslower edge, as first above 1nentioned; Fig. 2 is a similar view, showingthe tail gate adapted to swing open on a line located somewhat above itsImiddle; Fig. 3 is aside view of a portionof a truck-provided withmyimproved tail gate, showing theposition ofthev parts as indicated inFig. 1'; and Fig. 4t is a View similarfto.

"At each endof the tail gate, that is, at each side of the vehicle, are bolted apair of angle-irons LYR'NEW YORK, AssIGNoR r0 WILLIAM OSCAR smm- BOLT,OF'N'EW YORK, N.}Y. l1. I

8, forming between themja groove 9 (see Figs. 1' and v2). To the floorofthe body,

and extending rearwardly therefrom, are

eyes '10, each being the end of one of the leaves of hinges uponwhichjthe tailgateswings when it is in the position showni'n Figs. 1 and3. The other leaves, for the two intermediate hinges, are "formed bythe.

members ll bolted onto the tail gate (see particularly bers 11 isprovided with an eye similar to Fig. 1), each of which mem-- the eyes10, "and the hinges are completed '7 es which are For the twoexteriorvhinges the pair at the extreme ends of "the tail gate-the otherleaves are formed by members 13, which are provided with eyes ateachend. When the tail gate is in the position shown in Figs. 1 and .3,"pintles 12 are inserted through the eyes .m one through the eyes 10 attachedto the'tail gate, and pintles 14 t rough the eyes in the other ends ofthe members-13 and through perforations in the angle-irons 8. Under thisarrangement, the 'tail gate is adapted to end of the members 13 andswing downward upon itslower. edge into a lane approximately the same asthatof the '90 f oor of the carrying body, being prevented from fallinglower by the chain 15. .The tail gate, is secured in .its closedposition by swinging the link 35 into engagement with the eye 36,

When it is desired to arrange the tail gate sothat it may swing openfrom above so as to permit the discharge of the load underneath the tailgate when the carrying body is tilted, that is, according to thearrangement shown in'Figs. 2 and 4, the pintles 12 are removed from thehingesat the lower corners of the tailgate, formed by the eyes 10 andthe lower ends of the swinging member 13, and the said swinging membersare swung upward into the position shown in Figs. 2 and 4 and arethere'pivotally secured to devices attached to therear ends of the sidesof the carrying body. In the form of the body shownin the drawin s, anextra 01' additional side board 19 one on each side) is provided, towhich are securedla series of downwardly extending tongue's'20, thelower ends of which are held in sockets 21 as shown in Figs. 3 and 4.The rear ends of these additional side boards 19 are-protected by plates22 and to these and to the side boards are secured members 23 .each ofwhich has a pair of outwardly projecting perforated ears f 24, betweenwhich the upper ends of the members 13 lie when said, members are 7'swung intotheir upward position as'shown in Figs. 2andl4c and-thepintles "12 arethen inserted through said perforations in said ears andthrough the eyes in the ends of the swinging arms 13. The pintles 12 arethen removed from the intermediate hinges atthe the dumping of the loadwhenthe carrying I body is tilted; In order to prevent the tail 'ibottomof the tail gate and, as will be readily seen, the tail gate is then ina condition to beswung outward atI'the bottom, permitting gate fromswinging merely on the pintles 14, which it'mig'httend to do, and causeit and the swinging members 13 to swing from their'pivotal suspension attheir upperends,

swing together.

' I provide pins 30 adapted to pass throu h perforations in theangle-irons 8 and it e swinging members 13 and cause" same to '1Latche's16 pivoted 17 t5 the "ads, of the carrying body are provided, each of lwhich is adapted to engage with a stop '18 V ing the same from the stop18, and the on the tailgate; this latch and stop. serve to hold 'thetail gate closed, more particularly in the arrangement shown'i'n Figs. 2and 4, the" link 35'serving forthis purpose more particularlyinthearrangement shown in igs. 1 and'3. When itis desired to release the tailgate and allow the same to' open,

Whether it is arranged as shown in. Figs. 1 and3 so as to open at thetop or asshown in Figs. 2 and 4; so as to open at the bottom, the latch16 is raised into the position shown by the dotted lines in Fig. 4, thusdisengagink 35, .is freed from the eye 36, thus leaving the tail gatefree to open.

; The operation of my invention is as follows: 'It will be obvious thata vehicle proover the same; or as a dumpingtruck, in" 'which the body istilted to discharge 'the load, inwhi ch case the tail gate swingsoutward "fromabove and permits the load to escape underneath the'same.The first use of' the tailgate is shown in Figs. .1 and 3,

and the second use in Figs. 2 and 4. V

The advantages of'my invention will'be obvious fromwhathas beenabovesaid 1 ith regard to'its construction and mode 0 op eration. i
